Officials said at least 62 people were injured in the Wednesday evening rush-hour disaster. Twenty people were missing, according to the Minneapolis Star-Tribune, and 30 to 50 cars remain in the river, the U.S. Coast Guard said.
The Hennepin County Medical Examiner on Thursday morning said the confirmed death toll was four, lower than the nine deaths reported earlier.
Security camera video showed the Interstate 35W bridge’s center section collapsing into the river in less than four seconds. The northern end of the span appeared to drop first and the southern end followed.
CNN obtained the video from a source who asked to remain unidentified because they were not authorized to distribute it publicly
